DEBUG [extension/wp-toolkit] An error has occurred when decoding JSON by Zend_Json: Illegal Token
Trace: #0 C:\Program Files (x86)\Parallels\Plesk\admin\plib\vendor\plesk\zendframework\library\Zend\Json\Decoder.php(113): Zend_Json_Decoder->_getNextToken()
ERR [extension/wp-toolkit] Unable to fetch WordPress multisite flag for WordPress instance #1 ('') Reason: An error has occurred when decoding JSON returned by wp-cli: 'Illegal Token'
Cause
There are BOM symbols in %plesk_vhosts%example.com\httpdocs\wp-includes\functions.php file, which prevents correct functionality of Wordpress instance in WordPress ToolKit.
The issue is submitted as bug #EXTWPTOOLK-1583, which is planned to be fixed in one of the future Plesk updates.
Resolution
Until the fix is available use the following workaround:
-
Log into the server via RDP;
-
Download the attachment with the script which converts BOM symbols into UTF-8 and unpack it in C:/;
-
Open Command Prompt as Administrator and execute the following command, replacing example.com with the name of the domain where issue exists:
C:\> php.exe "C:\check_utf8.php" "%plesk_vhosts%example.com\httpdocs\"
